I’d argue that the examples you point out are a bit different, as in they are 
inherent aspects of the specific technologies and functionality that ARIN is 
charged with its stewardship of (in this case, IP and AS resources), but does 
not necessarily call out a specific technology other than those. 

As a counterexample, there are no references to BGP in the NRPM; while it’s 
highly unlikely that a new protocol will overtake it, there would be no needed 
changes to the NRPM to accommodate should that happen. More importantly, should 
there be a technical need and will to standardize on a new protocol to replace 
BGP, there’s zero concern that ARIN policy will slow the development or 
adoption of such a technology.

(True, the chances of BGP being eclipsed by a new protocol are probably lower 
than the chances of Ethernet being replaced, but I don’t think that dilutes the 
argument here.)

This is my main concern around the use “Ethernet” in this proposal - it’s not 
that we are simply acknowledging what is standard practice today, but I would 
never want ARIN policy to be a blocker for the adoption of new technologies, 
and the more specific we get about what technologies are required per policy, 
the higher that risk becomes.

Thanks,
